Methods The study included 127 women who aged between 16 and 18 years using Marvelon for 24 months and 115 women who aged between 16 and 18 years using nonhormonal contraception as control subjects. BMD of the lumbar spine and femoral neck were obtained using dual energy X-ray absorptiometry. Results After 24 months of Marvelon use, as compared with baseline, the mean BMD in lumbar spine and femoral neck were decreased by 0.30% and 0.61%, respectively. While in the nonusers group, the mean BMD were increased by 1.88% and 1.10%, respectively. Lumbar spine and femoral neck BMD in women who used Marvelon were not significantly different compared with the subjects who used nonhormonal contra- ception （P〉0. 05）. Conclusion Two years of Marvelon use had no significant effect on BMD, but it remains unknown whether longer than 2 years of use has a significant adverse effect on the attainment of peak bone mass.展开更多
目的初步评估单纯补肾健脾针刺法对老年男性原发性骨质疏松症的临床疗效。方法将60例首次确诊为原发性骨质疏松症的老年男性随机分为针刺组和假针刺组。针刺组选择双侧肾俞、脾俞、命门、足三里、关元穴和疼痛部位的阿是穴。假针刺组针...目的初步评估单纯补肾健脾针刺法对老年男性原发性骨质疏松症的临床疗效。方法将60例首次确诊为原发性骨质疏松症的老年男性随机分为针刺组和假针刺组。针刺组选择双侧肾俞、脾俞、命门、足三里、关元穴和疼痛部位的阿是穴。假针刺组针刺点为针刺组穴位旁开2寸处。手法进针,留针30 min,每周2次,3个月为一个疗程。评估指标为治疗前后两组患者的VAS疼痛评分、中医证候改善情况及两组患者腰椎及左侧股骨颈的骨密度(bone mineral density,BMD)值。结果经过3个月的治疗,针刺组的VAS疼痛评分较治疗前显著降低(t=16.307,P<0.01),而假针刺组并没有发生大的变化(P>0.05);治疗后,两组间的VAS疼痛评分差异有统计学意义(P<0.01)。治疗后,针刺组的中医证候改善的总有效率明显高于假针刺组(χ~2=33.61,P<0.05)。治疗后,针刺组的腰椎及左侧股骨颈BMD值较治疗前有提高趋势,但这种差异并没有统计学意义(P>0.05);而假针刺组腰椎及左侧股骨颈的BMD值较治疗前并没有发生大的变化(P>0.05)。结论短疗程的单纯补肾健脾针刺法可以改善老年男性原发性骨质疏松症患者的疼痛症状和中医证候,并且这种临床症状的改善要早于骨密度的改善。展开更多
目的探讨南宁地区壮族、汉族正常人群骨密度(bone mineral density,BMD)、峰值骨量(peak bone density,PBD)以及随增龄骨丢失率(rate of bone loss,RBL)的规律及临床意义。方法使用美国Hologic公司生产的双能X线吸收仪(dual energy X-ra...目的探讨南宁地区壮族、汉族正常人群骨密度(bone mineral density,BMD)、峰值骨量(peak bone density,PBD)以及随增龄骨丢失率(rate of bone loss,RBL)的规律及临床意义。方法使用美国Hologic公司生产的双能X线吸收仪(dual energy X-ray absorptiometry,DAX),对南宁地区壮族、汉族正常体检人群的20899名的腰椎L1~4、左股骨颈上段BMD进行测定,按检测不同部位、性别、年龄分组统计出PBD的均值±标准差和RBL(%)。参照WHO的规定,对≥50岁男性和绝经后女性与本数据库人群中同性别、同部位PBD比较,-2.5<T值<-1.0为骨量减少,T值≤-2.5为骨质疏松。结果 (1)各部位PBD出现在25~27岁,腰椎PBD男性为1.066±0.153,女性为1.025±0.095;左股骨颈上段PBD,男性为0.920±0.136,女性为0.796±0.132。(2)女性在47岁前BMD处于平台期,围绝经后BMD加速丢失,以腰椎尤为显著,年RBL在1.13%~2%;男性累计RBL随年龄逐渐上升,年丢失率约在0.21%~0.68%,但各年龄段左股骨颈上段的RBL始终高于腰椎。(3)以本地区人群数据库作为参照,男性骨质疏松检出率为腰椎3.1%,左股骨颈上段9.47%;女性腰椎48.8%,左股骨颈上段5.02%。结论南宁地区老年人发生骨质疏松性骨折风险女性明显高于男性,女性的腰椎、男性的股骨颈可能骨折风险更高。展开更多
